Case Report

Central retinal artery occlusion following staphylococcal orbital cellulitis

R M Bhola, S Dhingra, A G McCormick and T K Chan

Ophthalmology Department Royal Hallamshire Hospital Glossop Road Sheffield S10 2JF, UK

Eye. 2003 Jan;17(1):109-11.

History & Examination

• 51-year-old Indian male • No significant contributory medical history• 24-h history of progressive left periorbital pain and

swelling • Accompanied by fever and chills• VR 64 and VL HM• LE:

– pustular lesion at the inner aspect of the upper lid– periorbital swelling– complete ptosis– marked proptosis– haemorrhagic chemosis

Examination

• LE:– corneal oedema – patchy filling of the tributaries of the central

retinal artery and vein– superficial retinal opacification at the

posterior pole– absence of a cherry red spot at the macula

Management

• Intravenous acetazolamide• Ocular massage• Anterior chamber paracentesis • Unsuccessful at restoring retinal perfusion• VL deteriorated to NPL • MRI/ CT:

– soft tissue density infiltrate extending anteriorly around the left globe

– no sub-periosteal abscess– clear sinuses– no intracranial involvement

Management

• C/S pustular lesion– Staphylococcus aureus

• Orbital cellulitis responded to IV flucloxacillin and metronidazole

• Full blood count – increase in neutrophils and monocytes during the

acute illness

• Inflammatory markers returning to normal after the infection resolved

• Immunological and haematological investigations were all normal

Management

• FFA 1 week after confirmed retinal vascular occlusion with normal choroidal perfusion

• Six weeks later, fundal examination did NOT demonstrate disturbances in the retinal pigment epithelium consistent with choroidal ischaemia

Comment

• Acute arterial occlusion is an unusual but known complication of orbital cellulitis

• It has been demonstrated that following orbital inflammation, occlusion may occur at the level of the central retinal artery or occasionally at the ophthalmic artery

• In CRAO, there is typically a cherry red spot at the macula

• In this case, there was retinal whitening at the posterior pole– usually seen in ophthalmic artery occlusion

Comment

• Interestingly, FFA 1 week after the event demonstrated CRAO but the choroidal perfusion was deemed to be normal.

• This was supported by a fundal appearance 6 weeks later showing no evidence of previous choroidal ischaemia.

• It seems that the clinical appearance of a white posterior pole may not always signify ophthalmic artery occlusion.

Comment

• The origin of the infection was believed to be a pustular lesion on the inner aspect of the upper lid which grew Staphylococcus aureus.

• This is a known cause of orbital cellulitis, but its association with arterial occlusion has not been documented.
